People wanting lightweight stuff will use Busybox, so I think it's fine. And as said on IRC, if someone wants to use login utils from util-linux without PAM, then that someone should go upstream and fix this. > > Would it be possible instead that util-linux always uses the libuuid > > from the libuuid package? > > Not without heavy patching which doesn't look so simple for 2.22+ that > did a big rewrite in the autotools fu.

After: ./configure --disable-libblkid --disable-libmount --disable-deprecated-mount --disable-mount --disable-losetup --disable-fsck --disable-partx --disable-uuidd --disable-mountpoint --disable-fallocate --disable-unshare --disable-arch --disable-ddate --disable-eject --disable-agetty --disable-cramfs --disable-switch_root --disable-pivot_root --disable-kill --disable-last --disable-utmpdump --disable-line --disable-mesg --disable-raw --disable-rename --disable-reset --disable-vipw --disable-newgrp --disable-chfn-chsh --disable-sulogin --disable-su --disable-schedutils --disable-wall The build takes: real 0m11.406s user 0m35.654s sys 0m4.528s on my laptop. It certainly builds and installs a bunch more crap than just libuuid, but it's not too bad. Another solution is to apply the attached patch, and use the --disable-allprogs option. Then, it builds and installs only libuuid. It then takes: real 0m3.209s user 0m8.333s sys 0m1.196s Best regards, Thomas -- Thomas Petazzoni, Free Electrons Kernel, drivers, real-time and embedded Linux development, consulting, training and support. http://free-electrons.com -------------- next part -------------- A non-text attachment was scrubbed...
