I had to specify full path and then it works. But relative path (./my-tmp) does not work. For example this works. /root/git/xfstests-dev/src/idmapped-mounts/mount-idmapped --map-mount b:10000000:0:100000000000 /root/idmapped-testing/my-tmp /root/idmapped-testing/shifted But this fails. $ /root/git/xfstests-dev/src/idmapped-mounts/mount-idmapped --map-mount b:10000000:0:100000000000 ./my-tmp shifted Bad file descriptor - Failed to open ./my-tmp Not sure if this is a limitation of idmapped-mounts or this is expected. Thanks Vivek
