Hi EuAndreh, This feature was removed from Guix Home 10 months ago: https://git.sr.ht/~abcdw/rde/commit/a4b3a93b88f29eb4b37695e04e0ca200184fec28 I don't remember all the reasons, but it was slightly problematic. I'll name a few things, which come to my mind: =2D Due to implementation of guix services extension mechanism, it's necessary to pass the path to guix home directory to some services explicitly and instantiate them even if they not used. https://git.sr.ht/~abcdw/rde/commit/a4b3a93b88f29eb4b37695e04e0ca200184fec2= 8#gnu/home.scm-1-4 =2D It's hard to cleanup environment variables like PATH and similiar when GUIX_HOME_DIRECTORY changed. =20=20 =2D It was hard to know if and where the previous generation was installed, right now it can be easier, but some edge cases can pop up. For example if activation script called outside of `guix home reconfigure` or some other circumstances. If I remember something else, I'll let you know. I don't dissuade you, but not sure if abilitiy to move ~/.guix-home around worth the hassle. Aesthetically pleasant paths in the cost of development and maintaining a feature, which affects and complicates many places. =2D-=20 Best regards, Andrew Tropin --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQJDBAEBCgAtFiEEKEGaxlA4dEDH6S/6IgjSCVjB3rAFAmJzcjAPHGFuZHJld0B0 cm9wLmluAAoJECII0glYwd6wpA4P/A/wzuhFHV3uiq1JsCBvVs4eEks34guDKZx/ iWI11x9H01GS8aNdaT6y9fA1KjPlXqeDCKsRUnjHN3WAeRaHZ1n0ccogHtk/AaaC ZIP9nOSh839Uv87ukn1Gn9kC2JM/SV3kfnm9PpHDiWpdlodZcRSNahkS4mHgUGOB pUxU7D7kroGKID7hPhbdpTD2G3UsWVBn7cB4b4mTG/6YsFSySOMsLh01puu10DcY klzmndc8wGMsjrR1zSXK1wvDonOOzmuWNbHt3HCFCKQ0EwZqYZZj4oU8S+p7kMq5 H0xaJWTAKAvSEVX76efEO8wdTTUYSmQTedRoolsRkaeoQcOP+A6NVWlVjVLc+3wJ EAPf5PkHjjv7yJEJ7OtTOVM+eXhCp/mCkCzYu26QiY0AoAy30YNcXMce1vR8L/Qw rhiSPnS/g55nCgi1lYnjZ/7Rf0MR6woHZ4l1YE8Qhbwq2+iwZDdUG/1ijop2nRrk NJiZ+WhpfDIB8vZvwtGVxUEqne3mY+mCHDDaiS6LKs5PPu7RpfSJVG1f/1remLhG +9yx3hxk9Ur/LBcotlt2OKS1shKIkJfJsdQOuuJubaxvkMO5f8V2Ro0CVRWe0Egp E/zIGhQBRH0wtn0l0XlKwlBenTT1RbQaB93Hm4d9DDaLZcLAsgdTDi3PNNRQU6Aq OHOuU/SE =TBod -----END PGP SIGNATURE----- --=-=-=--
