minus-squareaurtzy@discuss.tchncs.delinkfedilinkEnglisharrow-up1·11 months agoIt appears that this is actually a Bash thing rather than a Guile thing: https://superuser.com/questions/132489/hostname-environment-variable-on-linux HOSTNAME is a variable that bash (but not other shells) sets by default. It is not exported. Since it’s not exported, it will not be inherited by env or any C program invoked from a bash shell. For more information about why, see the comment in this other answer which mentions that HOSTNAME is not required for POSIX compliance: https://superuser.com/questions/132489/hostname-environment-variable-on-linux/132500#132500 https://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html Curiously, I can reproduce this on my Guix System, but actually not on my Fedora system (where it is exported automatically), so I guess some distros choose to explicitly export the HOSTNAME variable?
