[...] Number of uids 2 unknown (0) nixbld (987) Number of gids 2 unknown (0) nixbld (980) Failed to read existing filesystem - will not overwrite - ABORTING! --8<---------------cut here---------------end--------------->8--- I was able to reproduce it on a CentOS 7 system and to strace the ‘mksquashfs’ process, and found that this had to do with access to SELinux extended attributes. Fixed in commit 53c594cb3f1f783fea18be6da23a863b00c14f5f. Thanks! Ludo’.
