The following environment variables influence the program behavior:
HOME is used to find xorriso and mkisofs startup files.
MKISOFSRC may be used to point the program to a mkisofs startup file.
SOURCE_DATE_EPOCH belongs to the specs of reproducible-builds.org. It
is supposed to be either undefined or to contain a decimal number which
tells the seconds since january 1st 1970. If it contains a number, then
it is used as time value to set the default of --modification-date=.
--gpt_disk_guid defaults to "modification-date". The default of
--set_all_file_dates is then "set_to_mtime". Further the "now" time for
ISO nodes without disk source is then set to the SOURCE_DATE_EPOCH
value.

Startup files and program options can override the effect of
SOURCE_DATE_EPOCH.
Be aware that by default xorriso puts its version information into the
Preparer Id field of the ISO 9660 Primary Volume Descriptor. This may
be desired in order to clearly define which xorriso version has to be
used for reproduction. But it may also be undesired because a wider
range of xorriso versions shall not be excluded from an attempt of
reproduction.
Use option -p with a text other than "@xorriso@" if you want to override
the default at first production time. This option may also be used to
explicitly set the preparer id as found in an ISO 9660 filesystem which
shall be reproduced by a different version of xorriso. The id can be
inquired by the generic xorriso command -pvd_info.
