It is true, bue 'xz' is required in other situations too. For example, CONFIG_KERNEL_XZ CONFIG_MODULE_COMPRESS_XZ CONFIG_INITRAMFS_COMPRESSION_XZ If we document the requirement for 'xz', we need to document the requirement for 'gzip', 'zstd', 'lzma', etc. for the same reason. So, I want to go only with 'tar' in this series. > Reviewed-by: Nicolas Schier <nicolas@xxxxxxxxx> > > > > + > > gtags / GNU GLOBAL (optional) > > ----------------------------- > > > > -- > > 2.39.2 > > -- > Nicolas Schier > > epost|xmpp: nicolas@xxxxxxxxx irc://oftc.net/nsc > ↳ gpg: 18ed 52db e34f 860e e9fb c82b 7d97 0932 55a0 ce7f > -- frykten for herren er opphav til kunnskap -- -- Best Regards Masahiro Yamada
