Hi, uploaded is
http://www.gnu.org/software/xorriso/xorriso-1.4.5.tar.gz MD5 245708a0530741dcb2cc30ee4fadaa29 Version timestamp : 2016.08.20.102601 Its -as mkisofs option --set_all_file_dates understands pseudo-timestamp "set_to_mtime", which changes atime and ctime immediately before writing begins. It is implemented as -find action "set_to_mtime". Users who want to apply it in finely controlled manner do outside mkisofs emulation: -find ...start_path... ...tests... -exec set_to_mtime -- I tested with debian-8.4.0-amd64-netinst.iso which has quite mixed timestamps: $ for i in " " c u ; do ls -ld$i /mnt/iso/README.mirrors.html ; done -r--r--r-- 1 root root 181263 Mar 21 22:25 /mnt/iso/README.mirrors.html -r--r--r-- 1 root root 181263 Apr 2 16:43 /mnt/iso/README.mirrors.html -r--r--r-- 1 root root 181263 Mar 23 02:17 /mnt/iso/README.mirrors.html After using it as input for xorriso -as mkisofs -o test.iso -R -J \ --set_all_file_dates set_to_mtime \ /mnt/iso and mounting the resulting test.iso, i get: -r--r--r-- 1 root root 181263 Mar 21 22:25 /mnt/iso/README.mirrors.html -r--r--r-- 1 root root 181263 Mar 21 22:25 /mnt/iso/README.mirrors.html -r--r--r-- 1 root root 181263 Mar 21 22:25 /mnt/iso/README.mirrors.html ------------------------------------------------------------------------- I did not change the interpretation of SOURCE_DATE_EPOCH yet. If you decide for the newer proposal, then apply this change: --- xorriso/parse_exec.c.orig 2016-08-16 15:15:26.786135631 +0200 +++ xorriso/parse_exec.c 2016-08-20 12:36:31.920225537 +0200 @@ -2584,7 +2584,7 @@ malformed:; 1900 + gmt->tm_year, gmt->tm_mon + 1, gmt->tm_mday, gmt->tm_hour, gmt->tm_min, gmt->tm_sec); xorriso->gpt_guid_mode= 2; /* Disk GUID from vol_uuid */ - strcpy(xorriso->all_file_dates, xorriso->vol_uuid); + strcpy(xorriso->all_file_dates, "set_to_mtime"); sprintf(xorriso->info_text, "Environment variable SOURCE_DATE_EPOCH encountered with value %s", sec_text); and tell me to do the same. (I still think that "Specification" in https://reproducible-builds.org/specs/source-date-epoch/ would justify strcpy(xorriso->all_file_dates, xorriso->vol_uuid); but would need some addition before it justifies strcpy(xorriso->all_file_dates, "set_to_mtime"); ) Have a nice day :) Thomas _______________________________________________ Reproducible-builds mailing list Reproducible-builds@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/reproducible-builds
