Sorry for all the questions...  |
Not sure if you still want some feedback but I went down this rabbit hole the other day. I closely followed your blog post and made a few small changes. For me the interesting part isn't so much how small the install is byte-wise, but how few packages can be installed to have a "usable" minimal system with no broken dependencies. This install comes in at 54 packages and 265MB.
A few things I did differently:
* I did not bother with ntp
* Used kernel-huge which negates the need for the mkinitrd package.
* Installed libevent as sftp requires that library.
* After the system was installed, I also saved /etc/localtime as /etc/Eastern, removed glibc-zoneinfo and copied /etc/Eastern back to /etc/localtime.
* I used the same trick to compress the kernel modules and /usr/doc as you did, but I used xz instead of gzip. This saves ~50MB.
* I deleted all of the non-English language man pages. (Could save a few more MB by just deleting the rest since the man-db package is not installed).
Now comes that part that is a little suspect. The system as installed will have some broken dependencies. The way I determined that is with the command:
Code:
find / \( -path /proc -prune -o -path /sys -prune -o -path /media -prune -o -path /mnt -prune \) -o -type f | xargs file | grep -i 'dynamically linked' | cut -d: -f1 | xargs ldd > /tmp/results.txt 2>/dev/null
I looked at /tmp/results.txt to see what was "not found". I determined that a few of the libraries from the aaa_libraries package had missing dependencies, but the libraries were not used by anything so I deleted the following:
Code:
rm /usr/lib64/libcups*
rm /usr/lib64/libldap*
rm /usr/lib64/libtiff*
rm /usr/lib64/libcurl*
rm -fr /usr/lib64/python2.7
rm -fr /usr/lib64/python3.9
At this point the system still has a few broken dependencies. If I recall correctly it was for
/sbin/tc and
/usr/bin/setpriv
I then installed the following in
/usr/lib64/microslack (basically copied from another system with a larger install):
Code:
lrwxrwxrwx 1 ang ang 18 May 7 06:57 libcap-ng.so -> libcap-ng.so.0.0.0*
lrwxrwxrwx 1 ang ang 18 May 7 06:57 libcap-ng.so.0 -> libcap-ng.so.0.0.0*

lrwxrwxrwx 1 ang ang 17 May 7 06:50 libpcap.so -> libpcap.so.1.10.1*
lrwxrwxrwx 1 ang ang 17 May 7 06:50 libpcap.so.1 -> libpcap.so.1.10.1*
-rwxr-xr-x 1 ang ang 348504 May 7 06:50 libpcap.so.1.10.1*

-rwxr-xr-x 1 ang ang 71560 May 7 06:44 libxtables.so.12.4.0*
After that I ran the following and rebooted:
Code:
echo "/usr/lib64/microslack" > /etc/ld.so.conf.d/microslack.conf
rm /etc/ld.so.cache
ldconfig
I then updated the following packages with upgradepkg so that i have a patched system running kernel 5.15.94:
aaa_base gzip kernel-huge kernel-modules openssh openssl-solibs tar util-linux xz
I then installed
wireguard-tools which did not require anything else.
I have another system where I did install ntp and all the requirements for slackpkg. I took the find command from above and wrapped it in a little script that uses slackpkg's file-search feature and finds the packages I need to install. It's not 100% fool-proof as sometimes it does not find the package you need (libXaw is one I recall as the base of the symlink does not actually match the library name). I basically keep running that script until there are no missing dependencies. I think the system came out to about 120 or so packages. Then with httpd and gcc it ballooned to something like 167.
I call it
reconcile.sh
Code:
#!/bin/bash
find / \( -path /proc -prune -o -path /sys -prune -o -path /media -prune -o -path /mnt -prune \) -o -type f | xargs file | grep -i 'dynamically linked' | cut -d: -f1 | xargs ldd > /tmp/results.txt 2>/dev/null
grep 'not found' /tmp/results.txt | sort | uniq | awk '{ print $1 }' | rev | cut -d. -f2- | rev > /tmp/missing-libraries.txt
COUNT=$(wc -l /tmp/missing-libraries.txt | awk '{ print $1 }')
if [ $COUNT == 0 ]; then
echo "No missing dependencies!"
exit
else
echo "We have work to do for the following missing libraries:"
cat /tmp/missing-libraries.txt
echo
fi
while read FILE
do
slackpkg file-search $FILE | grep uninstalled
done < /tmp/missing-libraries.txt | sort -V | uniq | awk '{ print $3 }' > /tmp/needed-packages.txt
echo "The following packages need to be installed:"
cat /tmp/needed-packages.txt
echo
echo "Press any key to continue."
read keystroke
while read PKG
do
slackpkg install $PKG
done < /tmp/needed-packages.txt
Anyway, hopefully someone finds this interesting (My first post in a few years!)
Minimal Install for Slackware 15.0
Thank for your help
