2) Do I support a 64 and 32 bit installation, or should it just be
32-bit? If it's a combination, how do I resolve the installation
conflicts (bin placement, etc).
Afaik, for libraries, kernel modules, etc. you place 32-bit variants
in base lib path, and 64-bit ones in amd64/. For executables you use
a copy of (or a hard(!)link to) isaexec in the base path, and place
32-bit binaries in i86/.
More generally, some package distros used directory symlinks like
32 -> ./i86/ ( or ./i386/ or ./i86pc/ )
64 -> ./amd64/
or
32 -> ./sparcv7/
64 -> ./sparcv9/
depending on CPU arch. I am not sure how that worked (with ld's
support or somehow else?) Probably *with* system preferences:
# crle
Default configuration file (/var/ld/ld.config) not found
Platform: 32-bit LSB 80386
Default Library Path (ELF): /lib:/usr/lib (system default)
Trusted Directories (ELF): /lib/secure:/usr/lib/secure (system
default)
# crle -64
Default configuration file (/var/ld/64/ld.config) not found
Platform: 64-bit LSB AMD64
Default Library Path (ELF): /lib/64:/usr/lib/64 (system default)
Trusted Directories (ELF): /lib/secure/64:/usr/lib/secure/64
(system default)
