Previously kexec-tools will pass "--compress zstd" to dracut. It will make dracut to decide whether: a) call mksquashfs to make a zstd format squash-root.img, b) call cmd zstd to make a initramfs. Since dracut(>= 057) has decoupled the compressor for dracut and dracut-squash, So in this patch, we will pass the compressor seperately. Note: The is_squash_available && !dracut_has_option --squash-compressor && !is_zsdt_command_available case is left unprocessed on purpose. Actually, the situation when we want to call zstd compression is: 1) If squash function OK, we want dracut to invoke mksquashfs to make a zstd format squash-root.img within initramfs. 2) If squash function is not OK, and cmd zstd presents, we want dracut to invoke cmd zstd to make a zstd format initramfs. is_zstd_command_available check can handle case 2 completely. However, for the is_squash_available check, it cannot handle case 1 completely. It only checks if the kernel supports squashfs, it doesn't check whether the squash module has been added by dracut when making initramfs. In fact, in kexec-tools we are unable to do the check, there are multiple ways to forbit dracut to load a module, such as "dracut -o module" and "omit_dracutmodules in dracut.conf". When squash dracut module is omitted, is_squash_available check will still pass, so "--compress zstd" will be appended to dracut cmdline, and it will call cmd zstd to do the compression. However cmd zstd may not exist, so it fails. The previous "--compress zstd" is ambiguous, after the intro of "--squash-compressor", "--squash-compressor" only effect for mksquashfs and "--compress" only effect for specific cmd. So for the is_squash_available && !dracut_has_option --squash-compressor && !is_zsdt_command_available case, we just leave it to be handled the default way.
