Did not enter the directory specified by %HOME%

smalltalkman commented 4 months ago

I wanted to specify the HOME directory before starting busybox, but busybox entered the path specified by BB_SYSTEMROOT.

# set BB_SYSTEMROOT=D:/gym/softwares/busybox
# set HOME=%BB_SYSTEMROOT%/home/root
# busybox_pre64 sh -l
D:/gym/softwares/busybox #
D:/gym/softwares/busybox #
D:/gym/softwares/busybox # echo $HOME
D:/gym/softwares/busybox/home/root
D:/gym/softwares/busybox #
D:/gym/softwares/busybox # pwd
D:/gym/softwares/busybox
D:/gym/softwares/busybox #
D:/gym/softwares/busybox # uname --help
BusyBox v1.37.0-PRE-5317-g54dbf0fa5 (2024-04-06 09:03:16 BST)

It seems to be related to the code here: https://github.com/rmyorston/busybox-w32/blob/758a72f55360a1f3a5400aeca29bc2ea0647bad1/shell/ash.c#L16242

Also, can I specify the HOME variable in /etc/profile? It would be very convenient if possible.

The directory specified by HOME must exist. Otherwise, it will enter the existing parent directory.

No, that isn't possible. It would be quite easy to add such a feature, but I'm a bit uneasy about the idea. Allowing /etc/profile to change HOME isn't how things work in Unix.
