This system is stripped and working! Probably no problem, if it works
now.
Thank you all who helped me.

Randy, I have used only these you listed. Perhaps later...

Good that there is no slash in the beginning, so it is assumed you are
not running the system to be stripped.

I have only modified the log files and added some other commands for
statistics, some after Bruce. Also, logged in k, not h (du).

Thanks, DJ.
I have a xz file backing up these four, but they seem not to have
been touched, perhaps already stripped in LFS build.

Thanks, Bruce.
Ticket created. Left for you to decide if priority should be low.

strip-bin totalseconds: 30
strip-lib totalseconds: 188
Totalseconds: 218
USED_AFTER - USED_BEFORE = -161340 (bin)
USED_AFTER - USED_BEFORE = -626516 (lib)
So, about 770M economy in space. Not much, but enough to really use
strip from time to time.
Thank you very much again (BDR).
Have to turn off all machines now.
[]s,
Fernando
