Well, amiga's current directory was the null string i.e. the bit between
the quotes in "" (compare unix "."), and extra "/" meant parent
directory (compare unix "..", but only sortof)

so unix "projects/interociter/../deathray"
would be amiga "projects/interociter//deathray"
and unix "cd ../deathray" would be amiga "cd /deathray"

The root of the current volume was called ":"
there were multiple volumes, the volume name being the part preceding
the ":" in an amiga absolute path. Unlike MSDOS, however, the current
volume was part of the current directory (i.e. current directory was
not per-volume).

For porting unix applications, the ixemul.library (amiga cygwin-like)
just stuck a virtual single root one level above the volumes, so
amiga-native work:projects would just become unix /work/projects

Actually, parsing of the path in AmigaOS could be filesystem driver
dependent: When "multimedia cdroms" started coming out in the 1990s
with HTML with embedded unix-style or msdos-style relative pathnames in
links, mount options were added to allow such alien paths for access
within cdrom filesystems so that the embedded relative links would
work.
