`duperemove` complains about `tmpfs` filesystems: "lives on an unsupported filesystem, please fill a bug" #327

Closed trofi closed 8 months ago

trofi commented 8 months ago

Ran duperemove against my root / and got the following reports:

# duperemove -q --batchsize=0 --dedupe-options=partial,same -rd --hashfile=/run/duperemove/root-dupes.db /
...
//dev lives on an unsupported filesystem, please fill a bug
//sys lives on an unsupported filesystem, please fill a bug
//proc lives on an unsupported filesystem, please fill a bug
//run lives on an unsupported filesystem, please fill a bug

These are usual tmpfs-like filesystems:

$ cat /proc/mounts | grep -P ' /(run|dev|sys|proc) '
devtmpfs /dev devtmpfs rw,nosuid,size=6592840k,nr_inodes=16479788,mode=755 0 0
proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0
tmpfs /run tmpfs rw,nosuid,nodev,size=32964200k,mode=755 0 0
sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0

Hello,

Ha yes, you are trying to process the entire rootfs I moved that message into the debug layer

Indeed, tmpfs and friends do not support deduplication, hence this message But I understand that it may be too verbose

Thank you for your report
