update slackware -current with script using rsync

jheengut · 07-24-2019, 10:39 AM

Hi,

I prefer to keep an updated /var/cache/packages in case some package has to be reinstalled and the internet is not available. This script helps in removing old packages in -current since slackpkg does not remove them automagically.

I would like some suggestions regarding this script

I have tested for over a year and it seems to be okay.

Not to dismiss what your script does, but have you tried the DELALL option in your /etc/slackpkg/slackpkg.conf? I don't have any files remaining in /var/cache/packages/ (I do have folders, just no files in them).

Code:

# If DELALL is "on", all downloaded files will be removed after install.
DELALL=on

My approach to keeping a local archive is detailed here with a further update here.

I also like having a local copy of the set of packages and files comprising Slackware 14.2, primarily so I can download them once and then use the local copy to update the several computers which I maintain. I intend to minimize the network traffic I cause to the mirrors.

I have a script for the downloading, but the script has only one important command:

Code:

#! /bin/bash
# filename: update_slackware.sh

echo ""
echo "-- Get the: 64 bit version of Slackware 14.2. --"
# This command gets all but: kdei, and testing.
rsync -ahv --stats --progress --partial --fuzzy --delete-after \
    --exclude='kdei' --exclude='testing' \
    mirror.slackbuilds.org::slackware/slackware64-14.2/ \
    /home/software/slackware64-14.2

The above rsync command deletes of all the files which do not exist on the mirror, after downloading the new files.

I want to keep the latest packages while removing the old packages.

The DELALL removes the downloaded files which I don't want to do.

My script is for -current only.

=================================================

Any stable version of Slackware has its own frozen package set.

All updates are downloaded into /var/cache/packages/patches/

Code:

ls  -lhRs /var/cache/packages/patches/
/var/cache/packages/patches/:
total 20K
4.0K -rw-r--r-- 1 521 521 552 Sep 20  2012 CHECKSUMS.md5
4.0K -rw-r--r-- 1 521 521 198 Sep 20  2012 CHECKSUMS.md5.asc
4.0K -rw-r--r-- 1 521 521 575 Sep 20  2012 FILE_LIST
4.0K -rw-r--r-- 1 521 521  14 Sep 20  2012 MANIFEST.bz2
4.0K -rw-r--r-- 1 521 521 224 Sep 20  2012 PACKAGES.TXT

In Slackware -current this is empty. All packages are downloaded into /var/cache/packages/slackware64/ or /var/cache/packages/slackware.

This script ensures my machines are keeping latest updates. Though if the slackpkg mirror has still not updated, some packages will be missing.

Ah, that makes more sense. I just keep a local mirror, which I point slackpkg to, but I guess that requires slackpkg to "download" (in reality, copy) the packages to its directory and then remove them afterwards.

I include "--preallocate" in the rsync command. Filesystems that support defragmentation operations automatically allocate minimally-fragmented file space in the destination.
