last time there was an update on slackware-current, I updated to latest kernel 4.1.6, but the next day , my init was reported as a corrupted lzma image.
yesterday I performed a rescue using a 32bit cd and later realized the mess I just did, I grabed a 14.0 64bit dvd and reinstalled only the a/ and wget. Later did a slackpkg reinstall.
at one time my root partition was completely full.

the funniest part was that kwin and some other programs were hard coded to a specific version of the lib nvidia_glsi.

ldd /usr/bin/kwin
libnvidia-glsi.so.346.59 => /usr/lib64/libnvidia-glsi.so.346.59 (0x00007fdb8ebda000)
