 @elvishjerricco:matrix.org | nikstur: Any chance you could help me with understanding some of the internals of the composefs stuff that the etc overlay uses? | 21:25:36 |
| @elvishjerricco:matrix.org | I was expecting to be able to getfattr -d - m '-' the files in the the erofs metadata image to see some overlayfs-related xattrs | 21:26:06 |
| @elvishjerricco:matrix.org | but I don't see any | 21:26:09 |
| @elvishjerricco:matrix.org | * I was expecting to be able to getfattr -d -m '-' the files in the the erofs metadata image to see some overlayfs-related xattrs | 21:26:35 |
| @elvishjerricco:matrix.org | Namely, I was expecting to see some trusted.overlay.metacopy and/or trusted.overlay.redirect xattrs | 21:27:50 |
| @elvishjerricco:matrix.org | huh, yea I can definitely see some of that in the strings output on the erofs | 21:54:12 |
| @elvishjerricco:matrix.org | so why can't I mount the erofs and getfattr to see them? | 21:54:34 |
