Hi all. After my earlier post, I ran an strace on the syslinux command I
was executing. In the output there is a mention of ld.so.preload, which
after doing some research I figured out that file pertained to Libsafe. It
then opens the floppy device like its supposed to, however then it
attempts writing to /tmp. When it can't do that it exits with an exit (1).
Anyone know if I actually need libsafe installed in order to use Syslinux
properly? I am kind of speculative about doing this after hearing about
what Chuck went through with it. Thx!
May you code in the power of the source,
may the kernel, libraries, and utilities be with you,
throughout all distributions until the end of the epoch.
