Dear BusyBox devs,
Could you take a look at this Alpine Linux issue?
https://gitlab.alpinelinux.org/alpine/aports/-/issues/13578
I believe that init command from BusyBox overrides HOME and TERM
environment variables that were set in boot params.
As a result, the following env vars that were set in boot params:
HOME=/root
TERM=linux
are changed to:
HOME=/
TERM=vt102
I suggest to check if HOME env var is set instead of hardcoding it:
putenv((char *) "HOME=/");
When it comes to TERM env var, a more sophisticated check is made:
#ifdef VT_OPENQRY
if (ioctl(STDIN_FILENO, VT_OPENQRY, &vtno) != 0) {
/* Not a linux terminal, probably serial console.
* Force the TERM setting to vt102
* if TERM is set to linux (the default) */
if (!s || strcmp(s, "linux") == 0)
putenv((char*)"TERM=vt102");
# if !ENABLE_FEATURE_INIT_SYSLOG
G.log_console = NULL;
# endif
} else
#endif
Maybe adding a CONFIG_CHECK_VT_OPENQRY in order to make this check
optional would be a good idea?
Please share your thoughts.
Regards,
jkm
