usbimg2disk.sh tweak
The usb-and-pxe-installers/usbimg2disk.sh script uses rsync to copy slackware packages to a USB flash drive (if requested through command line options). The flash drive will usually have the FAT32 filesystem which can only store timestamps in multiples of 2 seconds. If the Slackware packages being copied are on a Linux filesystem it is likely that their timestamps will not be quantised to 2 second intervals. As a result, subsequent runs of the usbimg2disk.sh script (to update the flash drive with the latest versions of packages) will unnecessarily re-copy many unchanged packages since the source and destination timestamps differ.
To stop this, could "--modify-window 2" be added to the rsync command in usbimg2disk.sh? A modify window of 1 could be sufficient in theory. However, I am unsure that a timestamp of (say) 01:02:03.8 would be rounded up to 01:02:04. If it were rounded down to 01:02:02 instead then a modify window of 2 will be needed. Since there's little reason to prefer 1 over 2 I would be included to go with 2 in order to be sure that it will have the desired effect. |
switch default package/other compression algorithm to zstandard
Suggest to switch installation package default compression algorithm to zstandard.
initramfs image also could be compressed with zstandard by default, Slackware generic kernel already has zstandard for initramfs support enabled (CONFIG_RD_ZSTD=y). It offers very fast decompression speed, in the order of GB+ per second. So system installation will happen much faster, especially with a good ssd storage. Compared to xz, zstandard can achieve close compressions ratio. https://facebook.github.io/zstd/ Considering the Arch Linux report on move to zstandard compression, I think the Slackware installation packages size will increase not more than 1 to 5 percent. https://en.wikipedia.org/wiki/Zstandard: "Arch Linux added support for zstd as a package compression method in October 2019 with the release of the pacman 5.2 package manager,[26] and in January 2020 switched from xz to zstd for the packages in the official repository. Arch uses zstd -c -T0 --ultra -20 -, the size of all compressed packages combined increased by 0.8% (compared to xz), the decompression speed is 1300% faster." |
Why should we do that?
5.11 is a non LTS kernel version. Quote:

Anyone having a problem with samba? I don't usually use it but geeqie binds to it and I get this error:
Code:
geeqie: symbol lookup error: /usr/lib64/libkrb5samba-samba4.so undefined symbol: krb5_set_default_tgs_ktypes, version krb5_3_MIT [solved] Reinstalled krb5 and that fixed it. Thanks, everyone! |

And 5.11.z is in /testing so people can install it from there if needed, so win/win! |
