Dan, Bruce, and Ken,
I've been following this thread with interest. I'm into my fourth LFS
build, using LFS 7.4.
For my previous three builds, I successfully use the package user hint
without any problems. Now I'm facing the same issues as Dan.
I tried building su from an old source at this link, starting at line 802:
I built it with GCC at the end of chapter 5 (I typed 'gcc -o su su.c'),
then copied it to /tools/bin.
When I got to chapter 6, as the root user in the chroot environment,
that copy of su would not switch users to the linux-libc-headers user I
created for the first package. I got the error:
bash: /tools/bin/su: No such file or directory
I then copied su from the host system and got the same results.
Dan, when you say that su didn't work for you. Did you get an error message?
