Bug 269864

Summary:	/rescue/zcat does not behave like zcat

Description Dave Hayes 2023-02-28 00:36:30 UTC

So when booting 13-STABLE (specifically commit 44a6088278ea3ae6e98b04d9863d7fdf033f26a3) I get the following:

 /rescue/zcat somefile.gz | dd ...
 zcat: somefile.gz already has .gz suffix, unchanged

It appears that zcat thinks it's gzip. I say this because

 /rescue/zcat -c -d somefile.gz | dd ...

works. At the very least, if this is not something I did mistakenly, this is a POLA violation.

Could be the same issue with getprogname() as in bug 269738, try updating to latest stable/13.

Comment 2 Dave Hayes 2023-03-02 04:54:01 UTC

Stable/13-dc1ba2a43 still has this issue, as a datapoint.

Comment 3 Yuri 2023-03-02 07:58:17 UTC

My bad, looks like the fix was MFCed just now (2023-03-02 02:56:05 +0000).

Yes Yuri is right. Please try latest stable/13.

The underlaying problem is same with PR 269738 .

Unfortunately the fix has landed in stable13 (before I got noticed about this PR), so the commit message does not include this PR .

The fix will be in upcoming release 13.2-RC1.

You can also try the latest build from https://artifact.ci.freebsd.org/snapshot/stable-13/ .

Thanks for the report!
