Package: debhelper Version: 10.6.4 Severity: normal Using "xz -1 --extreme" for udebs does make sense.
Or at least it did at some point, the 9 MiB memory required for decompression with the default -6 is likely no longer a problem today. But the same settings copied for -dbgsym do not make sense: Memory required for decompression is not an issue for -dbgsym. "xz -1 --extreme" is expected to have comparable (or even slightly worse) compression than the default "xz -6" while taking more compression time. Since the benefits of higher compression are smaller packages and shorter (sic) decompression time, using better compression than what is used for normal packages would not make sense. -dbgsym using the same compression as normal packages would therefore be a good choice.
