|
|
|

|
by-drive/DRIVE_LETTER -> ../../sdXN
|
|
|
|
|
by-label/VOLUME_LABEL -> ../../sdXN
|
|
|

What changed:
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
- posix_spawnp no longer falls back to starting the shell for unrecognized
|
|
|
|
|
files as execvp. For the reasoning, see
|

|
|
|
|
2024-01-17 12:39:50 +01:00
|
|
|
- FIFOs now also work on NFS filesystems.
|
2023-11-30 22:36:35 +01:00
|
|
|
|
|
|
|
|
- Enable automatic sparsifying of files on SSDs, independent of the
|
|
|
|
|
"sparse" mount mode.
|
2024-01-11 20:00:14 +00:00
|
|
|
|
|
|
|
|
- When RLIMIT_CORE is more than 1MB, a core dump file which can be loaded by gdb
|
|
|
|
|
is now written on a fatal error. Otherwise, if it's greater than zero, a text
|
|
|
|
|
format .stackdump file is written, as previously.
|
2024-01-09 14:12:31 +00:00
|
|
|
|
|
|
|
|
- The default RLIMIT_CORE is now 0, disabling the generation of core dump or
|
|
|
|
|
stackdump files.
